Who is Sarah Palin?

A disclosure
During the 2008 presidential campaign, the McCain campaign revealed that Governor Palin's 17-year-old daughter Bristol (pictured, right) is five months pregnant with the child of a boy the campaign only identified as "Levi." In a statement, Palin says her daughter and the baby's father plan to marry, and that the family will fully support the child. The news follows rumors that Governor Palin faked her earlier pregnancy and the baby she had in April, Trig (pictured, in Bristol Palin's lap), was really Bristol's.
